BRIEF DESCRIPTION OF DRAWING FIG. I is a side elevation of a muzzle loading handgun shown in lateral cross-section to illustrate the interior construction of the device.

FIG. II is a side elevation of the handgun taken from the same side as FIG. I to illustrate the cocking mechanism of the device.

FIG. III is a side elevation of the handgun taken from the opposite side as FIG. I to illustrate where the detonating cap is inserted into the device.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the drawings, there is illustrated a muzzle loading handgun which includes a barrel (16) and a stalk (10). The barrel (16) has an externally circular configuration and is made up of an outer barrel (1) of aluminum and a rifled inner barrel (2) of steel. The rear portion of the outer barrel (1) is counterbored to a larger Inner Diameter to provide a front barrier for the coil (12) to the remaining front portion of the outer barrel (1) is of a smaller bore than the rear portion.

The inner barrel (2) is of uniform outer diameter which is slightly smaller than the inner diameter of the front portion of the outer barrel (1 to allow for a sliding fit between the two barrels.

The rear portion of the inner barrel (2) is externally threaded and is screwed into the steel breech cover (3) which is correspondingly internally threaded. The outer diameter of the steel breech cover (3) is slightly smaller than the inner diameter of the rear portion of the outer barrel (1) to allow for a sliding fit between the two surfaces. The front portion of the steel breech cover (3) forms the rear barrier for the coil (12). The steel breech plug (4) is externally threaded and is screwed into the ear portion of the outer barrel (1) which is correspondingly internally threaded to form an anvil for the exploding cap. The steel breech cover (3) has a small hole centrally located in its diameter to allow the spark from the exploding cap to reach and ignite the powder inside the inner barrel (2). The front ends of the outer barrel (1) and the inner barrel (2) form a flush surface on a 29 countersink while the handgun (15) is in an uncocked position. These lengths were chosen so that in a cocked position the inner bar rel (2) will extend beyond the outer barrel (1) to make it very obvious that the handgun (15) is in the cocked position.

The reason for the 29 countersink at the front end of the barrel (16) is to prevent the accidental bumping of the front end of the inner barrel. (2) while the handgun (15) is in the loaded uncooked condition and thus accidentally firing the handgun (15). The coil (12) is located in the gap between the outer diameter of the rear portion of the inner barrel (2) and the inner diameter of the rear portion of the outer barrel (1). The coil (12) is horizontally restricted in the front by the counterbore in the rear portion of the outer barrel (1) and is restricted in the back by the front portion of the steel breech cover 3). The compressed coil (12) causes the inner barrel (2) to to thrown back onto the exploding cap on top of the steel breech plug (4) to fire the handgun (15).

The bottom of the outer barrel. (1) has a pin hole (17) in it to allow the pin (7) to fall into the notch (14) located in the bottom of the inner barrel (2) when the inner barrel (2) is moved into the cocked position. The pin (7) is caused to move into the notch (14) by a spring (8) which has its rear end attached to the pin (7) and its front end attached to the bottom side of the outer barrel (1) by means of a screw (9) which inserts into a threaded hole (18) and causes upward pressure on the pin (7).

The bottom of the outer barrel (1) has attached to it a trigger mount (5) behind the pin hole (17). In this trigger mount (5) is mounted the trigger (6). The trigger (6) has an extension which reaches under the spring (8) which holds the pin (7) in the notch (14) to cock the handgun (15). When the trigger (6) is pulled, the pin (7) is pulled out of the notch (14), releasing backward pressure on the inner'barrel (2) caused by the compressed coil (12), and the coil (12) pushes the inner barrel (2) back where it strikes the explosive cap on top of the steel breech plug thus firing the handgun (15).

The cocking pin (11) is fastened to the inner barrel (2). The right side of the outer barrel (1) has a horizontal barrel slot (19) in it to allow the cocking pin (11) to move the inner barrel (2) forward and cock the handgun (15).

The rear portion of the outer barrel (1 just in front of the front end of the steel breech plug (4), on the left hand side is a lateral cap slot (13). This cap slot (13) allows the explosive cap to be inserted into the chamber and therefore load the handgun (15).

I claim:

1. A muzzle-loading pistol having an outer barrel and an inner barrel, a trigger, and a sear, said outer barrel being of aluminum and closed at its rear end by a steel breech plug, said inner barrel being of steel and slidable within said outer barrel, said inner barrel having an apertured steel end cap at its rear end, said outer barrel having an opening in one side thereof permitting the insertion of an explosive cap between said breech plug and the end cap of said inner barrel, a coil spring surrounding said inner barrel and biasing said inner barrel wardly to compress said explosive cap between said breech plug and said end cap and ignite powder in said inner barrel through the aperture in said end cap.
